PEEK ( poly-ether-ether-ketone ) is a special high polymer material consisting of a ketone bond and two ether bonds in the main chain structure. It has unique high temperature resistance, excellent chemical corrosion resistance and other physical and chemical properties, which is a kind of semi-crystalline polymer material. Its structure is as follows:
PEEK film is made of PEEK polymer and it is a semi-crystalline high performance film of wide range applications. PEEK film has properties of high temperature resistance, light weight, good mechanical properties, good durability, excellent radiation resistance, hydrolysis resistance, chemical resistance, electrical insulation, wear resistance, good barrier performance, good flame resistance, low toxicity of combustion, low water absorption, halogen-free and good processing performance.
